This episode delves into the mystery of time, which feels linear and irreversible in our experience... but appears nearly reversible in fundamental physics laws. Discover how scientists define time through what clocks measure, how Einstein's theories introduced a more flexible concept, the connection between the "arrow of time" and the universe's evolution, and even the surprising link between time and dark matter. Is the time we experience real, or could it be an illusion? Tune in for a compelling look at time's deepest mysteries. Hosted on Acast. See acast.com/privacy for more information.
